Paleogenomic evidence for multi-generational mixing between Neolithic farmers and Mesolithic hunter-gatherers in the lower Danube basin
(Cell, 2017-05-25)[Abstract] The transition from hunting and gathering to farming involved profound cultural and technological changes. In Western and Central Europe, these changes occurred rapidly and synchronously after the arrival of ... -
Parallel construction of wavelet trees on multicore architectures
(Springer U K, 2016-10-05)[Abstract] The wavelet tree has become a very useful data structure to efficiently represent and query large volumes of data in many different domains, from bioinformatics to geographic information systems. One problem ... -
Parsing as Pretraining
(2020)[Abstract] Recent analyses suggest that encoders pretrained for language modeling capture certain morpho-syntactic structure. However, probing frameworks for word vectors still do not report results on standard setups ... -
PDE Models for the Pricing of a Defaultable Coupon-Bearing Bond Under an Extended JDCEV Model
(Elsevier, 2021)[Abstract] We consider a two-factor model for the pricing of a non callable defaultable bond which pays coupons at certain given dates. The model under consideration is the Jump to Default Constant Elasticity of Variance ... -
Perceptual Generalization and Context in a Network MemoryInspired Long-Term Memory for Artificial Cognition
(World Scientific Publishing Company, 2019)Abstract: In the framework of open-ended learning cognitive architectures for robots, this paper deals with thedesign of a Long-Term Memory (LTM) structure that can accommodate the progressive acquisition ofexperience-based ... -
Planetary Nebulae in Gaia EDR3: Central Star Identification, Properties, and Binarity
(EDP Science, 2021)[Abstract] Context. The Gaia Early Data Release 3 (EDR3), published in December 2020, features improved photometry and astrometry compared to that published in the previous DR2 file and includes a substantially larger ... -
Planificación y distribución óptima de cargas en un sistema de evaporadores industriales
(Comité Español de Automática, 2016)[Resumen] En este trabajo se presenta la resolución de un problema de asignación temporal de recursos, así como el reparto de cargas en varias líneas de evaporación industrial. Dichos evaporadores tienen diferente rendimiento ... -
Plastic Debris in Lakes and Reservoirs
(Springer Nature, 2023)[Abstract] Plastic debris is thought to be widespread in freshwater ecosystems globally1. However, a lack of comprehensive and comparable data makes rigorous assessment of its distribution challenging2,3. Here we present ... -
PlayNet: real-time handball play classification with Kalman embeddings and neural networks
(Springer, 2024)[Abstract] Real-time play recognition and classification algorithms are crucial for automating video production and live broadcasts of sporting events. However, current methods relying on human pose estimation and deep ... -
Poly(Boc-acryloyl hydrazide): the importance of temperature and RAFT agent degradation on its preparation
(Royal Society of Chemistry, 2019)[Abstract] Poly(acryloyl hydrazide) is a versatile polymer scaffold readily functionalised through post-polymerisation modification with aldehydes to yield polymers for biological applications. However, its polymerisation ... -
Polymer-Induced Biofilms for Enhanced Biocatalysis
(Royal Society of Chemistry, 2022-07-21)[Abstract] The intrinsic resilience of biofilms to environmental conditions makes them an attractive platform for biocatalysis, bioremediation, agriculture or consumer health. However, one of the main challenges in these ... -
Polymorphism in Non-Fullerene Acceptors Based on Indacenodithienothiophene
(Wiley, 2021)[Abstract] Organic solar cells incorporating non-fullerene acceptors (NFAs) have reached remarkable power conversion efficiencies of over 18%. Unlike fullerene derivatives, NFAs tend to crystallize from solutions, resulting ... -
Los primeros robots manipuladores aéreos
(Comité Español de Automática, 2016)[Resumen] En este artículo se describen los primeros robots manipuladores aéreos dotados con brazos robóticos de seis grados de libertad y capacidades de percepción y planificación que se han desarrollado en el mundo. Estos ... -
Probability of default estimation in credit risk using mixture cure models
(Elsevier, 2024-01)[Abstract]: An estimator of the probability of default (PD) in credit risk is proposed. It is derived from a nonparametric conditional survival function estimator based on cure models. Asymptotic expressions for the bias ... -
Probing Tyrosine Nitration with a Small TbIII-Metallopeptide
(Wiley, 2023-06-06)[Abstract] Tyrosine nitration, a post-translational modification (PTM) that takes place under nitrosative stress conditions, occurs through a non-enzymatic peroxynitrite-mediated reaction. Although protein nitration has ... -
Production and characterization of an extracellular acid protease from thermophilic Brevibacillus sp. OA30 isolated from an Algerian hot spring
(MDPI, 2018-04-12)[Abstract] Proteases have numerous biotechnological applications and the bioprospection for newly-thermostable proteases from the great biodiversity of thermophilic microorganisms inhabiting hot environments, such as ... -
Progress toward Equitably Managed Protected Areas in Aichi Target 11: A Global Survey
(Oxford University Press, 2019)[Abstract]: The Convention on Biological Diversity Aichi Target 11 requires its 193 signatory parties to incorporate social equity into protected area (PA) management by 2020. However, there is limited evidence of progress ... -
Prototype of an Entity Recognition System for Antimicrobial Resistance Data Management
(Universidade da Coruña, Servizo de Publicacións, 2023)[Abstract] Often, a study or research process requires the analysis of large volumes of information in the form of unstructured text. This task consumes a large amount of time and resources of the human experts in charge ... -
Quantifying the role of individual flood drivers and their correlations in flooding of coastal river reaches
(Springer, 2019)[Abstract:] Flooding in coastal river reaches is the result of complex interactions between coastal and inland drivers. Flood hazard assessments need to consider how these drivers interact in space and time, for which a ... -
